2025 New York Mets season

The 2025 New York Mets season was the 64th season of the New York Mets in Major League Baseball, their 17th at Citi Field, their fifth under majority owner Steve Cohen, and their second under manager Carlos Mendoza.

On July 19, the Mets retired the number 5 worn by former captain David Wright and inducted him into the Mets Hall of Fame during a pre-game ceremony before a 5–2 loss to the Cincinnati Reds at Citi Field. Wright became the 10th individual to have his number retired by the Mets, and only the second, along with Tom Seaver, to be inducted into the team's Hall of Fame on the same day.

Although the Mets opened the season with a 45–24 record through June 12, the best record in MLB at the time and the second-most wins through the first 70 games in franchise history (behind only the 1986 team that won 49 of its first 70 games and went on to win the World Series), and attaining a 96.2% odds to make the playoffs, the team collapsed down the stretch. They finished 38–55 the rest of the way and endured three separate losing streaks of seven or more games. They became only the third team in the Wild Card era to start 45–24 or better and still miss the postseason, joining the 2002 Red Sox and 2003 Seattle Mariners. The team also suffered their most lopsided series defeat in franchise history, getting outscored 30–4 from June 27–29 by the Pittsburgh Pirates.

The Mets were the only team in the 2025 season to go winless when trailing after the eighth inning, going 0–70. In addition, the Mets went through a 60-game stretch where David Peterson was the only starter to last six innings, a dubious distinction going back to 1901. On September 17, Dom Hamel became the 46th pitcher used by the Mets in 2025, setting a new MLB record for the most pitchers used by a single team in one season, surpassing the previous record held by the 2024 Miami Marlins. The record was later tied by the 2025 Atlanta Braves on September 28. The Mets also blew 4+ run leads for three consecutive games for the first time in franchise history.

On a positive note, Juan Soto joined the 30–30 club on September 9, and also broke his career high for hitting his 42nd home run of the season on September 19, eventually hitting his 43rd of the season nearly a week later on September 24. Francisco Lindor also joined the 30–30 club on September 23, marking the second time in Mets history that two teammates achieved the feat in the same season, following Howard Johnson and Darryl Strawberry had done so in 1987. In addition, Pete Alonso hit his 253rd career home run, breaking Darryl Strawberry's Mets franchise record of 252 home runs. Nolan McLean was promoted from AAA on August 13, and is the Mets pitcher to earn a win in his first four career starts.

The Mets finished the season 83–79, marking their second consecutive winning season (their first such stretch since 2015–2016). They ended with the same record as the Reds but lost the head-to-head tiebreaker, as Cincinnati won the season series four games to two. However, despite the Reds losing 4–2 to the Milwaukee Brewers in their final game on September 28, the Mets were eliminated from playoff contention for the seventh time in nine years after a 4–0 loss to the Miami Marlins the same day.

This was the final season for Pete Alonso and Edwin Díaz with the Mets, as they signed with the Baltimore Orioles and Los Angeles Dodgers in the offseason, respectively.

The New York Mets drew an average home attendance of 39,775, the 5th-highest of all MLB teams.
